Serial no. of nero
A serial # for nero must be purchased. If you have had Nero 6 installed in the past and did a reinstall then this information may still be in your windows registry. There are several Key finder programs available for free, and they scan your computer for serial number keys. If you are familiar with using the windows registry then the serial number should be located in "HKEY_LOCAL_MACHINE\SOFTWARE\Ahead|Nero-Burning ROM\Info". This location may vary depending upon your installation settings, but it should be relatively similar to what I have listed. There are also key generator programs which are illegal to use in the USA, as they violate the DMCA.
